With reference to Figures 1, 2, 3 and 5 the housing or casing of the vending machine, with which 5 the attachment is to be used in connection with, is indicated at H]. The major portion of the front of housing In is open, as indicated at II. The remaining portion of the front of housing in is closed by a wall member I2. includes a pair of side walls l3, I4, 2!. top wall IS, a rear wall I6 and a bottom H.

The vending attachment, in accordance with this invention, is attached to housing I0, constitutes a closure for the open front portion H and extends outwardly with respect to the wall member [2. The attachment is arranged between the side wall l3, top wall l5, bottom I1 and member l2 of housing I0.

With reference to Figures 1 and 5: The attachg0 ment includes a front section formed of a vertically disposed rectangular part 2 I, a pair of oppositely outwardly inclined side parts 22, 23, a rearwardly extending upwardly inclined top part 24, a rearwardly inclined bottom part 25, a forwardly extending trough 26 integral with the outer face of the lower portion of the rectangular part, and a rectangular elongated slot 21 transversely of part 2| in proximity to the bottom of the latter. The slot 21 opens into the trough 26 above the bottom of the latter. The purpose of slot 21 will be hereinafter set forth. The side part 22 has a vertical shoulder 28 adjacent its rear edge.

When the section 20 is arranged in position relative to housing Ill the part 24 abuts top wall I5, the part 22 extends against the inner face of wall 13, the shoulder 28 on part 22 abuts the forward edge of wall l3, part 23 extends to oppose the inner edge of member I 2 and the part 25 seats on bottom ll. Suitable means, not shown, is employed for locking section 20 with housing Ill.

With reference to Figures 1, 2, 3 and 5: There is arranged within the section 20 a vertically disposed open bottom combined guide and storage structure 29 providing a series of vertically disposed parallel storage compartments: 30 open at their bottoms. Thestructure 29 includes a container formed of a rear wall 3|, a top wall 32, a. pair of side walls 33, a series of spaced vertically disposed parallel partitions 34 corresponding in height to that of the wall 3| and a front wall 35 of less height than that of the wall 3| and is formed at its lower end with a forwardly extending right angular disposed flange 36. The rear wall 3| and side walls 33 are formed from one '55 The housing i0 10 length of material. Arranged below the walls 3|, 33 and 35 is a horizontally disposed stationary plate 31 extending forwardly to below flange 36, rearwardly from wall 3| and laterally with respect to walls 33. The upper face of plate 31 aligns with the lower wall of slot 21. The side Walls 33 have integral with the lower portions of the outer faces thereof angle pieces 38 which rest upon and are anchored to the upper face of plate 31 whereby the bottom edges of said side walls seat directly upon the upper face of plate 31. The rear wall 3| is of less height than the side walls 33. The upper end of rear wall 3| is flush with the upper ends of the walls 33 thereby providing, in connection with plate 31, a groove 39 at the rear of said storage compartments 38 which extend from one side wall 33 to the other side wall 33. The compartments 38 are provided by thecoaction of the rear wall 3 side walls 33, partitions 34 and front wall 35. The partitions have their lower edges seated directly upon the upper face of plate 31. There is positioned upon the plate 31, forwardly with respect to wall 35, a bar 40 formed on its inner side with a series of spaced parallel vertical grooves 4| which receive extensions 42 on the partitions 34. The side walls 33 also extend into grooves 4|. This arrangement prevents the buckling or bending of the partitions. The lower face of bar 40 is formed with a groove 43 of a width corresponding to the distance between one side wall 33 to the other side wall 33. The groove 43, in connection with the plate .31 and partitions 34, forms outlets for the passage of the articles 44 which are to be selectively dispensed from the compartments 30. The flange 36 on the lower end of front wall 35 seats upon bar 40 and is hinged therewith, as at 45, whereby the wall 35 may be shifted away from the side walls 33 for the purpose of having access to the compartments 38. The top wall 32 is soldered or otherwise secured upon the upper ends of the walls 3|, 33 and the partitions 34. The top wall 32 carries a resilient latch 46 for detachably securing the front wall 35 in closure position with respect to the front of the compartments. Positioned upon the plate 31 and arranged against the rear wall 3| is a bar 41 (Figure 5) constituting a combined guide, stop and retainer element for a purpose to be referred to. The bar 41 has enlarged end portions 48 and a reduced intermediate portion 49. Hold-fast means 50 extend through the end portions 48 for anchoring bar 41 to plate 31. The lower face of the bar 41 is formed with a series of parallel grooves 5| (Figure 4) for the passage of ejectors to be referred to. The upper walls of the grooves 5| are flush with the bottom edge of rear wall 3|. The grooves constitute guides for the ejectors, to be referred to. The side walls of said grooves 5| prevent the ejectors from shifting laterally with respect to their path of travel in either direction.

Arranged rearwardly of the wall 3| of the structure 29 is a series of oscillatory operating levers 52 (Figure 4) for a series of ejectors 53. The number of levers and ejectors correspond to the number of compartments 30. The levers 52 are of like construction and each consists of an upper and a lower arm 54, 55 respectively (Figures 1, 2 and 3) disposed at an angle with respect to each other. The arm 54 is of materially greater length than the arm 55. The levers are pivoted at the point of joinder of the two arms thereof on a. stationary pivot rod 56 mounted in supports 51, 58. The arm 54 depends from the arm 55. The latter extends rearwardly at an upward inclination from the arm 54 and has connected to its rear end a controlling spring 59 depending from a support 68, secured to the top wall I5 of housing H). The lower end of the arm 54 is extended between a pair of oppositely disposed spaced parallel angle pieces 6| secured upon the upper face at the rear end of an ejector 53. The lower end of arm 54 (Figure 1) is slotted as at 62. Carried by the pair of angle pieces is a pivot 63 which extends through slot 62. The arm 54, between its transverse median and its upper end has adjustably secured thereto a rearwardly extending pointed combined stop and releaser element 64 for the lever.

Each ejector 53 is in the form of a rectangular slide 65 which travels upon the upper face of the plate 31 through a groove 5| at the bottom of a compartment and extends, when ejecting or vending an article, to the forward face of bar 48. The angle pieces 6| and pivots 63 form parts of the ejectors.

Arranged rearwardly of and spaced from the operating levers 52 (Figures 1, 2, 3 and 4) is a selector assembly for the levers 52. The assembly comprises a selector bar or element 66 formed (Figures 6, '7 and 8) with a set of spaced vertical parallel slots 61, 68, 69 and 10. The bar 66 is of oblong contour standing on its lower lengthwise edge 1|. The latter has depending therefrom a pair of outer and an inner depending lug indicated at 12, 12' and 13 respectively. The lugs are arranged in spaced relation. The lug 13 has attached thereto one end of a controlling spring 14 for bar 66. The latter is slidably mounted in the upper ends of a pair of spaced brackets 15, 15 attached to the frame 16 of the vending machine when the attachment is used. Associated with the bar 66 is a shifting lever 18 therefor which is pivoted intermediate its ends, as at 19, to a lug formed on and extending rearwardly from a depending portion 88 of a horizontally disposed yoke 8| secured to the rear of the upper ends of the brackets 15, 15. The forward end of lever 18 is arranged below the edge 1| of bar 66. The forward end of lever 18 has a curved nose 82 which is adapted to engage the lug 12 and shift the bar 66 for a purpose to be referred to. Attached to the lever 18 is the other end of spring 14. The latter tends to maintain the nose 82 in abutting engagement with lug 12. The lever 18 has its rear end arranged below a slotted link 84 which is pivoted, as at 85, to the rear end of the controlling lever 86 of the attachment. The lever 18 has attached to its rear end a slidable screw 81 which extends through the slot 88 in and slides on the link 84. Fixed at one end to the screw 81 is a controlling spring 89 for normally holding screw 81 clear of the end 90 of the slot 88. The other end of spring 89 is anchored to the pivot 85. The controlling lever 86 includes a vertical intermediate part 9|, an upper horizontally disposed rearwardly extending straight part 92 disposed at right angles to the upper end of part 9| and a horizontally disposed rearwardly directed hook-shaped part 93 extending in an opposite direction with respect to part 92 and also at right angles to the intermediate part 9|. The part 93 is arranged above the lower end of the part 9|. The lower end of bracket 15 is provided with a bearing 93' for the lower end of part 9|. The upper end of bracket 15' has a rearwardly extending bearing 94 for the upper portion of part 9|. The side wall |3 of housing I8 is formed with a clearance 94' for the bar 66 (Figure 4).

The controlling lever 86 is operated from the controlling mechanism 95 (Figures 6 and '7) of the vending machine with which the attachment is employed. The said controlling mechanism is of the weil known type disclosed by Figures 1, 2, 11 and 12 of Patent 1,767,603, indicated on the drawings of said patent by the reference characters 133 to 139 and 141 to 157 and as described in lines 116 to 130, page 3, and in lines 1 to 82, page 4 of said patent. The controlling mechanism, as referred to, includes what may be termed a slidable spring controlled rack and a set of slides and which are indicated on the drawings of this application at 96, 99 respectively. The part 93 of the lever 86 permanently bears against the front portion of the rack 96, and is normally held in such position by a spring 9'! which is attached to yoke BI and to the lever I8. On the operation of the vending machine with which the attachment is employed, the rack 96 moves forwardly acting on part 93 of lever 86 for shifting it to transmit motion to the lever I8 whereby the latter will be shifted away from lug 12 against 7 the action of spring 14. Carried by the bracket I5 below the bar 66 is an adjustable set screw 91 for arresting the sliding movement of bar 66 in a direction towards rack 96. The screw 97 is adapted to coact with the lug 12 to obtain a function hereinafter referred to.

The attachment includes an operating mechanism which is common to all of the ejectors. The said ejectors operating mechanism includes a normally stationary horizontally disposed spring controlled U-bar 98 (Figures 1, 2, 3 and 5) functioning when active to operate a selected ejector. The normal position of bar 98 is as shown in Figure 1, that is over and free of connection to plate 3?, as well as bearing against the lower ends of the arms 54 of the levers 52. The sides of bar 98 are indicated 99, I99. The arm 99 (Figure 5) is formed with a wide rear portion I9I provided with upstanding spaced bumper and trip lugs 92, I93 respectively. The bumper lug I92 is offset laterally with respect to the arm 99. The trip lug I93 is pointed and is arranged at the rear end of arm 99. The arms 99, I99 are formed with openings i9 9 for the purpose of securing the rear end of bar 99 upon a shaft I95 which is journaled in bearings I99, l9'l. A pair of operating springs I 9i" is provided for the bar 98. These springs are mounted about shaft I95 and each has one end bearing against one of the sides of bar 98 and its other end bearing against the lower face of plate 31. The shaft I95 is arranged slightly above the rear of plate 31.

The attachment includes a combined elevating restoring trip mechanism for the ejectors operating mechanism and which consists of a shiftable lever arm I99 (Figures 1, 2 and 3) which is pivotally mounted on the shaft I95. The-bumper I92 (Figure 2) is positioned in the path of movement of the forward side edge of lever arm I98. Pivotally connected to the lever arm I98, in proximity to, but above the arm 99 is a trip member E99 which extends rearwardly with respect to the rear end of arm 99 and is formed on and intermediate the ends of its bottom edge with a shoulder H9. The rear portion of member I99 is reduced and of curved contour. The shoulder H9 is for coaction with the trip lug I93 for a purpose to be referred to. Arranged below and spaced rearwardly adjacent with respect to bar 98 is a bracket III (Figures 1, 2 and 3) carrying an adjustable member II2 upon which the member I99 slides when in the position shown in Figure 3.

The attachment includes an automatically releasable safety mechanism or device to prevent the operation of the operating mechanism for the ejectors until the selector bar of the selector assembly has been adjusted to the desired point for selection of that ejector or ejector device which is to be operated. The attachment also includes a manually releasable locking mechanism for the ejectors operating mechanism. It is necessary to release the safety mechanism or device and the locking mechanism before an ejector device may be operated to discharge the selected article or card.

The automatically releasable safety mechanism or device includes (Figures 1, 2 and 3) a retainer IE3 formed with an upstanding nose H4 at its forward end. The rear end of retainer H3 is pivoted, as at I I 5, to the lower end of an inclined upstanding main operating bar II 9 which is mounted intermediate its ends upon a pivot Il'l carried by a plate I l9 anchored to the inner face of side wall I3 of housing I9. The forward end of retainer II 3 is pivotally connected with the upper end of lever i923, as at II 5'. Carried by plate I I8 is a pivot H9 upon which is mounted a spring controlled locking bar I29 which inclines upwardly from front to rear. The bar I29 has a reduced forward end edge I2! constituting an abutment for a purpose referred to. The rear end edge I22 of bar I29 is beveled. Mounted in close proximity to its upper end upon pivot i ii is a shiftable spring controlled depending releasing lever I23 formed with a lateral flange E24 on its lower portion for the purpose of shift ing bar H9 against the action of its controlling spring. The upper end of lever I 23 has'a for- Wardly directed enlarged angularly disposed part 525 provided with a vertically disposed threaded opening I26. Mounted in the opening I29 is an adjustable shifter I21 for the locking bar i29. The shifter i2! is arranged over the edge I22 of bar I29 whereby when the lever I23 is shifted forwardly against the action of the controlling spring I28, the shifter i2! will be moved clear of edge I22 to enable the rear portion of bar E29 to be moved upwardly on its pivot due to the action of controlling spring I 28 to arrange the bar I29 in looking position. The bar I29, when in its locking position, has its edge I2I abut the nose II4 on retainer II3 as is shown in Figure 2. The rearward movement of lever I23, due to the action of its controlling spring I28 will provide for the shifter I2! engaging edge I22 to move the rear portion of bar I29 downwardly for the purpose of shifting end edge I2! of said bar I29 clear of nose II4 thereby automatically unlocking the safety mechanism or device.

The lever I23 is shifted against the action of its controlling spring I28 by an element of the vending machine with which the attachment is used. As shown, by way of example, the means employed for shifting lever I23 indicated at I29, is in the form of the well known horizontally disposed oscillatory bar employed in coin controlled vending machines of known type, and

which is as indicated at 74 on Figures 3, 4, 5 and 6 of Patent 1,854,479. The bar I29, which corresponds to bar 74 of Patent 1,854,479, is operated by the means employed for operating the bar 74 referred to, or in other words the bar I29 corresponds to the oscillatory bar 74 of Patent 1,854,479.

The manually releasable locking mechanism includes a locking bar I30 which is eccentrically mounted on pivot H9. The bar I30 inclines upwardly from front to rear, is rabbeted at its forward end to form a nose I3! and a shoulder I32 and is provided at its rear end with a hook I33. That portion of bar I30 extending rearwardly from pivot H is of materially less length than that portion extending forwardly from said pivot. A controlling spring for bar I30 is indicated at I35 and which is attached to hook I33. The bar I30 is offset intermediate its ends as at I35. Extending through the offset part of bar I30 is an upstanding link I33 pivoted to bar i30, as at I31. The link I33 extends a substantial distance above bar I30 and is pivotally connected, as at I38, to a lever arm I39 which is fixed upon the inner end of a shaft I40, journaled in and extending through the plate IIS and side wall I3 of housing I0. The outer end of shaft I40 carries a push member I4I for rocking the shaft I40 clockwise against the action of controlling spring I34. Suitable stops I42 (Figure 1) are provided for limiting the movement of member MI in opposite directions. When the locking mechanism is in non-released position the forward end of bar I30 will overlap the rear upper corner of lever I08, as shown in Figure 2. On shifting shaft I40 from member MI in a clockwise direction lever arm I39 will be elevated, carrying link I36 therewith, which in turn will elevate the forward portion of bar I30 on its pivot whereby the rabbeted end of bar I30 will be moved clear of the upper end of lever I08 whereby the latter is released for actuation.

The main operating bar I I6 is adjustably connected at its upper end, as at I43, to a controlling spring I44. The plate [I8 carries an adjustable stop M for the bar H3. The plate IIB has an opening I45 which registers with clearance 94'. The articles shown in the compartments 30, by way of example, are cards. The stack of cards in each compartment may have mounted thereon a weight. The thickness of an ejector slide 65 is slightly less than that of a card.

The operation of the attachment is as follows: When the vending machine with which the attachment is employed is operated on the insertion of a coin it provides, first, the actuation of the mechanism 95 thereof and on the actuation of the said mechanism the rack 95 moves forwardly carrying the part 93 of lever 86 therewith whereby lever 83 will cause nose 82 to move away from lug I2 and apply tension to spring I4, and at this point bar 529 of the vending machine moves in a direction to engage and move lever I23 to an extent to have flange I24 engage the rear edge at the lower portion of bar II6 for moving the said portion forwardly to the dotted line position shown in Figure 2 whereby the elements I08, I09 and H3 will assume the full line position (Figure 2) toprovide for the element I08 bearing on the bumper lug I32 and forcing U-bar 98 down against plate 31 thereby forcing the arms 54 of levers 52 forwardly to move the elements 60 clear of bar 65 and allow the latter to shift to position lug 12 against nose 82. At this point the locking bars I20, I30 are in engaged position, as shown in full lines, Figure 2. At this point the operating handle of the vending machine, with which the attachment is employed, releases the mechanisms of said machine. At this point, bar I29 moves back slowly and when bar I29 moves to about three fourths of its return movement,

just about at the point before the shifter I2'I engages the edge I22 of bar I20, the rack 96 of the vending machine, which has its movement controlled, drops back rearwardly the distance of one, two or more teeth, which in turn, enables the part 93 of lever 86 to move back, whereby the spring 91 will maintain the part 93 in engagement with rack 96, which in turn, will enable for the coaction of lever I8 and lug I2 to slnft bar 69 in a direction towards rack 96. The distance of the shift of bar 66 is determined by the extent of the rearward shift of rack 96. On the shift of bar 66 in either direction one of the openings or slots therein is arranged to allow an element 64 to move therethrough. Such element 64 is carried by that ejector device which is to be operated. After the bar 66 has been shifted to the desired position it remains there until the attachment is operated again. When the bar 66 has been shifted to the desired position, the bar I29 has arrived at the extent of its rearward travel which allows lever I23 to assume the full line position in Figure 3, whereby said lever I 23 will act upon the safety mechanism to release it and at this point the manually operated locking mechanism may be released by operating the member I M in a direction to provide for the clockwise rocking of shaft I40. After the safety mechanism and the manually operated locking mechanism have been released the lower portion of main bar H6 is moved rearwardly by its controlling spring and shifts elements I08, I09 and H3 to the full line position shown in Figure 3, whereby the trip lug I03 will engage shoulder H9 and cause the raising of the U-bar 98 to the position shown in Figure 3. At this point the selected ejecting device which is to be operated will assume the position shown in Figure 3, that is forwardly of U-bar 98 and in alignment with the article which is to be ejected thereby. Upon the completion of the rearward travel of the lower portion of the main bar I I6, the trip lug I03 has been moved clear of shoulder H0 whereby the U-bar 08 is released from its position shown in Figure 3 and acts to operate the selected ejector device. The operation of the U-bar 98 is caused by the springs I08 and these latter provide for the U-bar 98 assuming the full line position shown in Figure l and which acts to hold the levers 52 in their normal position before selection.

The manually operated locking mechanism may be released at any time, that is before or after the release of the safety mechanism, but the operation of the attachment cannot be had until after the safety mechanism has been released on the complete operation of the vending machine.
